PF-2 CHARCOAL FILTERS
The function of the charcoal filter element is to remove any chlorine in the fresh water flush
water supply. It also removes any particulate matter. The charcoal filter we use removes
99.7% of the chlorine. Beware when buying other charcoal filters. If they don’t specify the
percentage of chlorine removed, don’t use them. The cheap ones in most cases will only
remove 60 or 70%. Also, there are aftermarket filters which are very close to, but not exactly,
the same dimensions that will not seal properly in the housing. The membrane can only
handle small amounts of chlorine for short periods without damage. The chlorine will damage
the bonding agent in the membrane in a very short time. So if you skimp on the charcoal filter
you will toast a $1625.00 membrane on the first flush. The other factor is the flow rate that the
filter can handle. Because the chlorine is deactivated by a chemical reaction with the charcoal,
it must remain in contact with the charcoal for sufficient period of time for the reaction to be
complete. The filter we use can handle 2 gallons (7.5 liters) per minute flow, and are good for
5000 gallons (12,000 litres) at 2 GPM, or six months,
whichever comes first
. Regardless of
the flow the charcoal loses its effectiveness after six months.
